I was watching a video review by The Urban Prepper on the Thrunite Catapult V6. It was one of the more detailed reviews I've seen, and it had very practical details. (Not all detailed reviews are practical).
One detail that interested me was his use of Civil Twilight distances in rating a flashlight. I think we can all agree that distance ratings on flashlights are somewhat useless, and give no indication of what to expect in real world situations. If I'm understanding this correctly, this calculation gave the distance at which we would see an object in the evening as if it was right after the sun goes down. When things are still pretty light out. This to me is tremendously more practical than the bs distances all flashlights have printed on the box.
Are there other reviewers using this metric? And, don't you think this is something that should be standardized and used by all companies?
Btw, what I typically have done is quartered the distance rating on a flashlight to give me an idea of what to expect. For example, if the rating is 400m, I'll expect to see reasonably well out to 100m, in optimally dark conditions of course. And probably 50m if there are other light sources around. These distance ratings don't take into account other factors like other light sources that can obstruct your view, etc.
Just wondering what other people think on this....
